Abstract

The parental origin of de novo deletions leading to the cri-du-chat syndrome has been investigated. Since the cri-du-chat syndrome is correlated with deletions involving the short arm of chromosome 5 (5p), DNA fragments known to detect restriction fragment length polymorphisms (RFLPs) along 5p were used to establish whether the paternal or the maternal chromosome had suffered the deletion. In cases where only one parent was available, somatic cell hybrids were used in conjunction with RFLP analysis to determine the origin of the deleted chromosome. The deleted chromosome 5 was of paternal origin in 20/25 cases.
